Revision No : 2

SEMICONDUCTOR

TECHNICAL DATA

BIPOLAR LINEAR INTEGRATED CIRCUIT

500mA POWER LOW DROPOUT REGULATOR

The KR52SXXXM/F is an efficient linear voltage regulator with very low

dropout voltage(Typically 10mV at light loads and 350mV at 500mA)

The KR52SXXXM/F can be enabled, or shut down by a CMOS or TTL

compatible signal. When disabled. power consumption drops nearly to zero.

Dropout ground current is minimized to help prolong battery life. Other key

features include reversed battery protechion, current limiting, over temperature

shutdown, and low noise performance with an ultra-low-noise option

FEATURES

High Output Voltage Accuracy : 1%

Built-in ON/OFF control Terminal

Built -in Over Current , Over Heat Protection Function

Reverse-Battery Protection

APPLICATIONS

Laptop, notebook, and palmtop computers

Cellular telephones and battery-powered equipment

Consumer and personal electronics

PC Card VCC and VPP regulation and switching

SMPS post-regulator/dc-to-dc modules

High-effciency linear power supplies
